Considerations for Protective Stabilization in Community General Dental Practice for Adult Patients with Special Healthcare Needs

Sydnee E. Chavis, DMD; Erica Wu, DDS, MS; and Stephanie M. Munz, DDS

Protective stabilization (PS), a method of medical restraint, has been utilized to evaluate and treat non-cooperative patients, such as patients with special healthcare needs (SHCN) or pediatric patients, in medical and dental settings.¹ PS is a method of physical restraint that involves the partial or complete immobilization of a patient's head, body, and/or extremities for a finite time period.^1-3 This restraint is applied in dentistry for assessment and treatment purposes in patients who are unable to cooperate or remain still for care.^1-5 The existing literature is based more in pediatric populations, but this information can be viewed from the lens of application for adults with SHCN.^1,2,6 In adult populations, PS is predominantly used for patients with SHCN whose developmental, acquired, intellectual, or physical disabilities result in behavioral and/or movement difficulties that challenge routine outpatient dental care.⁷ Examples include persons with autism spectrum disorder (ASD), cerebral palsy (CP), tardive dyskinesias, and generalized cognitive impairment or developmental delay.^1-3,5

Dental care has been shown to be the most unmet healthcare need for adults with SHCN.^8-10 PS has been suggested throughout the literature as a modality to facilitate improved access when other treatment options are unsuccessful, unavailable, or contraindicated.^5,6,11-13 Glassman et al stated that general dentists serve as access points for oral care for adults with SHCN who may benefit from use of PS for evaluation and/or treatment.^3,12 Application of PS may facilitate a more accurate assessment if complete treatment is not possible, and may then also facilitate an improved and thorough referral.^2,12

PS previously was one of few options to enable dental management for adults with SHCN.¹⁴ However, increased safety, monitoring, and accessibility of conscious sedation techniques and general anesthesia, as well as improvements and intentions in other behavior guidance techniques such as habituation and desensitization, provide alternative methods for treatment that are currently more widely and well accepted than PS.^15-17 Due to improvements in alternative behavior methods, shifts in attitudes have occurred among the healthcare community regarding use of PS.^14,18 For example, in the United Kingdom, PS is no longer a legal method of care.^14,19 However, within the literature PS still remains a controversial topic. The use of PS reportedly can be traumatic for patients and is perceived to be no longer in accordance with the standard of care with increased access and improvements in alternative techniques.¹⁸ Yet PS is supported in the literature as a viable treatment modality to facilitate care for adults with SHCN in the community when other options are contraindicated, unsuccessful, or unavailable and when limited treatment of short duration is required.^2,3,12

This scoping review article frames the use of these protocols and compiles the literature for the use of PS for adults with SHCN. The authors stratify what has been published regarding PS techniques, patient/guardian education and consent, indications, contraindications, clinical team considerations, and documentation and maintenance of PS.

Methods

A comprehensive literature review was completed to evaluate the application, clinical guidelines, and perceptions of PS, as well as its application for adults with SHCN. The literature search was conducted with searches in Ovid Medline, Embase, and Dentistry and Oral Sciences Source using the search terms as follows: "protective stabilization," "dentistry," "restraint," "patient positioning," and "immobilization." The searches were completed with these terms individually and in various combinations with the Boolean operators "AND" and "OR." Searches were completed in 2017, 2018, 2019, and 2020 to accommodate new research and literature.

Of 298 results, 29were relevant to the use of active or passive restraint in providing care to pediatric patients or adults with SHCN based on the selection criteria outlined in Figure 1. These articles were selected based on the following inclusion criteria: (1) relevance to the application of PS for adults with SHCN, (2) published in English language to avoid translation bias, and (3) published 1990 or later to maintain contemporary relevance.

Articles selected were first reviewed for relevance by title and abstract, followed by full article review of those selected by title and abstract. Articles were included based on agreement by the research team. If there was disagreement among the team, those articles in question were re-reviewed until consensus was obtained.Articles selected consisted of original research, clinical guidelines, statutory code, and commentary surrounding PS (Table 1). Source papers were also reviewed from references of literature obtained from the search.

PS Techniques

Active restraint involves physical immobilization by a healthcare provider and team, parent, or guardian, while passive restraint involves the use of a mechanical stabilization device for immobilization (Table 2).^1,2,6 Both are forms of PS. Active restraint can include head holds, therapeutic holds, and hand/arm or leg guarding. Passive restraint is implemented by utilizing a device, such as a Papoose Board^®(Olympic Medical Corporation), mouth prop, blanket, or arm and/or wrist straps to hold a patient's head, body, and/or extremities.^2,16 The conventional Papoose Board has individual straps for a patient's arms, an ankle strap to secure the legs, and wraps around the patient's body and a stabilizing board with Velcro^® secured wrap. Passive restraint implies the patient is secured with these devices. Positioning devices may assist in PS. These include wheelchair head supports, pillows, mouth props, and arm rests. Active and passive restraint may be utilized at the same time for patient care, depending on the clinical circumstance.^2,16

Education and Consent

Patient and guardian education regarding PS is necessary prior to its implementation.^13,16,20,21 The patient and/or the patient's legal guardian must be educated regarding the purpose, methods, and equipment used.^20,22,23 Education is an important part of obtaining informed consent, and full understanding of PS indications, benefits, risks, and alternatives prior to consent is required.¹³ PS is not highly accepted compared to alternative methods of behavior management such as voice control, habituation, and sedation methods.^6,17 However, according to studies by Frankel and Kupietzky, when presented in a constructive, positive, and comprehensive manner, there is increased acceptance, which can allay the negative stereotypes of PS and facilitate acceptance.^11,24 When the relative risks and benefits of PS are discussed independently as well as comparatively with other behavior modification modalities, patients and guardians are able to appropriately weigh the risks of PS versus the benefit of the immediacy of care PS can provide.^14,24-26

When providing education about PS, the following items should be explicitly discussed: (1) general behavior limitations to provide safe assessment or treatment and indications for use of PS; (2) methodology of PS use, including demonstration of devices; and (3) the psychological impact of PS use. Regarding the latter item, it should be noted that: PS may provide a sense of security; parents/guardians should be involved in active restraints for patient comfort when possible²⁶; and there is potential for patient discomfort, stress, and an adverse response.^{2,13,17,21,24}

Informed consent demonstrates a decision on the part of the patient and/or legal guardian for a procedure.²⁷ This process ensures the patient and/or legal guardian are aware of the implications and process of PS and that patient beneficence, non-maleficence, and autonomy are prioritized and maintained even for patients who are not able to consent for themselves.^{13,20,22,23,28} The use of PS is a dynamic process and consent for its use can be withdrawn at any time.²³

According to the American Academy of Pediatric Dentistry (AAPD), written informed consent for PS should be obtained every time it is used in addition to written consent for the concurring dental procedures.²³ When possible, written informed consent should be obtained prior to its use, so the designated consenting party can make an informed decision without the risk of a decision under duress.^23,29 Informed consent does not have an explicit duration or expiry, but many protocols define a finite length of time between consent and implementation for validity.^22,30 However, prior to implementation of PS, the provider should reconfirm consent and review benefits, risks, and alternatives with the patient and/or guardian, as well as document the updated consent.^13,22,23,31 Often times guardians will help with active PS, which is an act of implied consent for the procedure.^13,23,32 According to Schuman et al, if explicit consent is not obtained and documented, PS can be legally construed as criminal assault and battery.³³

While PS is often utilized for patients who do not make their own medical decisions, patients with physical or movement disorders who are not cognitively impaired may request PS to prevent untoward movements during treatment. Informed consent should still be obtained for the use of PS in this scenario despite the implied consent.²³

Patient selection is an important consideration when utilizing PS.^2,34 It is intended to facilitate treatment, but can heighten aggravation, aggression, stress, and/or discomfort for some patients.^26,34 According to guidelines published by the American Academy of Developmental Medicine and Dentistry (AADMD) and Nelson, for patients who demonstrate increased disturbance by vocal or physical means, such as those with a history of trauma or psychiatric diagnoses, PS can potentially contribute to more harm and trauma than benefit.^2,34

Indications for Use

Thoughtful consideration is necessary before implementing PS for dental care. The risks and benefits of PS must be evaluated critically against alternatives, and use of PS must reflect greater benefit to the patient than potential risk.^17,34 Per AADMD and AAPD clinical guidelines, PS should only be used for appointments/assessments of short duration or urgent procedures for uncooperative patients.^1,2,4 Techniques should limit untoward movements of the head, body, and limbs during treatment to allow for completion of treatment and should prevent injury to the patient and care team.^2,34,35 Additionally, PS should be tolerable by the patient without causing harm.^6,34 It is important to note the distinction between general patient discomfort in accordance with limited cooperativity versus the infliction of physical or physiological harm or trauma with the use of PS.^8,21,36 According to Hirayama et al, PS may be used with sedation methods to further improve patient comfort and safety without negative impact on patient recovery.³⁷

PS should be considered in adults with SHCN when it will facilitate safe and efficient completion of minimally invasive procedures or accurate assessment for necessary treatment, as stated by Nelson, Costa, and Davila.^15,34,35 PS may also be used in conjunction with oral anxiolysis, nitrous oxide, or moderate sedation to increase patient comfort and cooperation for treatment.^3,8,14 In emergent circumstances, PS can be used to manage dental urgencies/emergencies when systemic disease implications exist and other options such as sedation and general anesthesia are not available or timely.^2,14,34,38 According to Nelson, PS is intended for use in the outpatient dental setting when a patient is unable to tolerate or cooperate for treatment and other less invasive attempted modalities have been unsuccessful and insufficient.^6,14,34 It may be considered for patients in which conscious sedation medications or general anesthetics are contraindicated or unavailable in acute situations.¹⁸ Such contraindications can include allergy or adverse reactions to sedation medications or concerns for other comorbidities from a cardiopulmonary, neurological, renal, hepatic, or respiratory standpoint.^3,26,34 Sedation and general anesthesia may not represent safe or realistic options for routine dental care, such as recall visits.^13,34,39 According to Nelson and Newton, PS can be used as an alternative to reduce the need for more invasive methodologies for dental treatment needs.^8,34 Dougall states that clinicians should act in the best interest of the patient for care-the risks of neglected, untreated dental disease can supersede the risks and disadvantages of PS in those circumstances where alternative methods may be impossible or untimely.^8,28,40 However, when utilizing PS, clinicians must maintain an ethical standard and exhibit a mindful, professional attitude toward the patient to ensure his or her best interests.^20,40

During the COVID-19 pandemic, access to care for this patient population is even more limited. Alternatives to PS such as nitrous oxide, general anesthesia, and anxiolysis/sedation are more limited due to heightened personal protective equipment (PPE) requirements, concerns for aerosol-producing procedures, limitations on elective procedures, and reallocation of supplies and personnel.⁴¹ PS may serve as an access point for patients of this population to obtain timely care despite limitations due to the pandemic.

Lastly, PS may be the most cost-effective modality in a setting where there are limited financial resources or limited insurance coverage for outpatient sedation or general anesthesia.^15,42 Treatment under general anesthesia for significant dental needs has been shown to be more cost-effective than treatment under in-office sedation when treatment may take several appointments, in which case PS may enable some care.⁴³ However, financial reasons alone are not an indication for the use of PS.^1,2,15,42,43

Contraindications for Use

According to AADMD, AAPD, Nelson, and Costa, PS is contraindicated in scenarios in which the risks outweigh the potential benefits, the providing team is not comfortable or trained in utilizing PS, or when written informed consent is not provided by the patient, their legal guardian, or a durable power of attorney.^1,2,15,23,34 If a provider is not comfortable using PS, or a patient or guardian explicitly declines its use, PS should not be implemented.¹⁸

Contraindications include: a patient who is cooperative, a patient for whom immobilization can cause physical harm due to a physical or medical condition, and a patient who requires lengthy appointments and significant treatment to be completed in a single visit.^{2,20,21,31,34} PS should not be applied in a manner that is physically or unduly psychologically traumatic, or where it is not legally permitted.¹⁹ It is important to acknowledge that PS is used for patients who may not be inherently cooperative, and thus, the person may resist.^2,4-6,20 Implementation may be uncomfortable with resultant resistant behavior, but the clinical distinction between discomfort and physical or psychological harm is critical.

Thoughtful patient selection for use of PS with or without sedation is crucial, and PS should not be implemented for patients for whom it will heighten trauma and anxiety without the use of concomitant sedation.⁴⁴ This must be assessed and acknowledged by a trained provider implementing PS.³⁶ The patient's well-being is the highest priority. Patients with intellectual or developmental disabilities may not be cooperative for treatment with PS, but if they express physical pain, psychological pain, or severe discomfort, either physically or verbally, PS should be discontinued and alternatives should be considered.^2,5,22,31,34

Team Philosophy of Care

To implement PS in the outpatient dental setting, the provider and clinical staff should be trained in the safe and proper methods of its use, including how to transfer a patient to the dental chair, how to position the patient, how to apply the devices, and how to stabilize the patient without causing harm or trauma.²⁶ Training should include didactic components as well as hands-on methods/simulation.^{2,16,36,45,46} The extent of formal training providers and clinical staff receive varies across the field of dentistry.⁴⁵ This training may be acquired in school or clinical practice, but several resources, such as the American Dental Assistants Association, are also available that provide this specific training for the clinical team.⁴⁷ These include online seminars and didactic training through professional organizations, as well as didactic and hands-on training through continuing education courses.^1,48,49 A united, informed, educated, and trained clinical team is paramount to the safe and effective administration of PS.^14,50

According to Kupietzky and Ram, much of the negative perception of PS stems from its overuse by clinicians, poor patient education, and poor patient selection.²⁴ A well-trained clinical team should have the expertise and capacity to ensure that patients and their guardians are properly educated and informed on the use of PS, that it is used appropriately and efficiently, and its use causes minimal disturbance or trauma to the patient.^1,2,24,34

Documentation and Maintenance

As stated by Glassman et al, documentation of PS use is very important, and should include indication for PS, informed consent, type of immobilization device used, duration of use, and patient response to use.^3,12,44 This not only protects the clinician legally, but also aids in future use of PS by having a reminder of effective procedures and patient reactions.^1,8,13,26,27 PS devices should be maintained based on manufacturer's recommendations.²⁶ When not in use, immobilization devices should be stored in a closed space away from view in the event that the devices may invoke discomfort with sight.³⁴

Conclusions

Access to dental care remains a significant issue for adult patients with SHCN. Access to care is currently somewhat limited due to the COVID-19 pandemic. The increase in alternative behavioral and pharmacologic modalities provides viable alternatives to the use of PS that are more readily accepted among clinicians, patients, and guardians than PS. PS may still facilitate a timely, safe, effective, and efficient means of completing dental care or obtaining an accurate assessment for necessary dental care when other alternatives are not available or feasible.

Patient safety, autonomy, and beneficence must be maintained when implementing PS by a trained and unified clinical team that understands the intentions and implications of PS. More research on the implications and effectiveness for use in adults is recommended with a focus on a customized decision-making and assessment strategy to elevate patient safety and clinician diligence.
