Obstructive sleep apnoea and perioperative medicine: a growing concern.

Obstructive sleep apnoea represents a sizable public health and economic burden. Owing to rising obesity rates, the prevalence of obstructive sleep apnoea is increasing, and it is a condition that is significantly underdiagnosed. Exacerbated by the COVID-19 pandemic, the backlog of elective surgeries is also sizable and growing. A combination of these factors means that many patients due to have surgery will have obstructive sleep apnoea, either diagnosed or otherwise. Patients with obstructive sleep apnoea have a significantly increased risk of operative complications, but the evidence base for optimum perioperative management of these patients is limited. This article reviews sleep apnoea, its prevalence and its impact on operative management and perioperative outcomes for patients. The evidence base for screening and treating undiagnosed obstructive sleep apnoea is also comprehensively assessed. Finally, a pathway to manage patients with possible undiagnosed obstructive sleep apnoea is proposed, and areas for further research identified.

Making the case for spirometry as part of the perioperative multidisciplinary team assessment.

Chronic obstructive pulmonary disease (COPD) is a leading cause of morbidity and mortality and is significantly underdiagnosed in the community. Respiratory impairment is a key risk factor for perioperative morbidity and mortality. The National Institute for Health and Care Excellence (NICE) does not recommend routine spirometry before major surgery. However, in this article, we present the potential benefits of targeted spirometry in high-risk patient groups. Of 183 patients who underwent targeted preoperative spirometry, 25/70 (35.7%) of those with airflow obstruction had no previously known respiratory diagnosis. Of patients with known COPD, 20/46 (43.5%) were not prescribed optimum inhaled therapies for their degree of lung function deficit. Knowledge of lung function in respiratory disease helps to optimise patients perioperatively and facilitate shared decision making regarding the benefits and risk of surgeries. We propose that targeted spirometry should be used as part of the perioperative multidisciplinary team assessment of selected patients.

Perioperative comprehensive geriatric assessment: what do we need to know?

As a consequence of an ageing population greater numbers of elderly patients are presenting for both elective and emergency surgery. These older patients typically present with an increased burden of age-related problems and multimorbidity, which is associated with an increased risk of adverse postoperative outcomes. Traditional preoperative assessment models are adept at discerning patients' suitability for anaesthesia and surgery, but there is minimal focus on improving postoperative outcomes. Comprehensive geriatric assessment is a multidisciplinary approach used both to assess existing 'known' pathology and to screen for previously undiagnosed issues across medical, functional, social and/or psychological domains. This diagnostic phase then leads to the development and implementation of an individualized 'optimization' strategy across these domains. There is emerging evidence that comprehensive geriatric assessment and optimization in the surgical setting leads to improved outcomes, and it is reasonable to conclude that it would benefit the patient's long-term health.

Shared perioperative decision making: a shift in the doctor-patient paradigm.

The high-risk surgical patient only constitutes approximately 4% of the elective non-cardiac surgical population but contributes to the vast majority of in-hospital deaths following surgery. This, in conjunction with a high morbidity rate, can lead to a perioperative pathway fraught with challenges. It is incredibly difficult to anticipate which complications may arise and the risks involved before surgery. It is for this reason that patients need to be engaged in the decision-making processes regarding their perioperative care involved before major surgery. A combination of good medical practice, medicolegal influences and a governmental drive have begun to result in a shift away from paternalistic medicine to a shared decision-making approach. This article defines shared decision making, explores its benefits and limitations and addresses the relevant legal literature.

Perioperative medicine, interventions in surgical care: the role of replacing the late-night review with daytime leadership.

As the ambitions of surgery have continued to develop, it has resulted in medical advancements that challenge the current paradigms of hospital medicine. Patients previously deemed unsuitable for surgery are now undergoing potentially lifesaving treatments, but are nonetheless still being managed within a model of care that fails to meet their individual needs. Termed 'high risk', these patients, who are frequently elderly or with multiple comorbidities, embark on a surgical journey that is often fragmented and disjointed. Such patients contribute a startlingly high mortality and morbidity rate for non-cardiac elective surgery during the perioperative period, and as a result provide an added demand on already strained hospital resources. 'Perioperative medicine' has been proposed as a possible solution to this problem as it attempts to create a bespoke patient-centric model of care from the moment the need for surgery is identified, through to patient recovery. It is envisaged that the role of a perioperative physician would be to oversee this journey, uniting varying specialties along the way to ensure the best possible patient outcomes.
