Individuals with musculoskeletal conditions awaiting orthopaedic surgery consultation: an untapped opportunity for patient health management?

OBJECTIVE

To describe the health characteristics, condition-specific measures, chronic disease risk factors, and healthcare and medication use over time of individuals with musculoskeletal conditions awaiting orthopaedic surgical consultation. Study importance: Musculoskeletal conditions are highly prevalent in the general population and often coexist with chronic diseases. However, little is documented about the overall health of this group. This study describes the health of these individuals, with particular emphasis on modifiable risk factors of chronic disease.

STUDY TYPE

A repeated measures longitudinal cohort study of individuals referred for orthopaedic consultation across three time points (2014, 2015 and 2016).

METHODS

This study was undertaken in the orthopaedic outpatient service of a public tertiary referral hospital in New South Wales, Australia. Participants were aged 18 years and older and were referred for and awaiting orthopaedic surgical consultation for a musculoskeletal condition (back, neck, hand or wrist pain, or hip or knee osteoarthritis). Measures included patient demographics, condition-specific indicators (e.g. pain, disability, quality of life [QoL]) and chronic disease risk factors (e.g., excess weight, smoking).

RESULTS

The mean age of participants was 57.7 years, and 7.3% identified as Aboriginal and/or Torres Strait Islander. Back (43.1%) and knee (35.0%) pain were the most prevalent conditions. At baseline (N = 1052), participants reported moderate pain (mean numerical pain rating scale score of 6.4, standard deviation [SD] 2.4) and QoL (Physical Component Score of 32.7, SD 10.7; Mental Component Score of 46.6, SD 13.3). Chronic disease risk factors were highly prevalent, with 74.6% of participants having three or more. For most measures, there were only small changes over time.

CONCLUSION

Individuals with musculoskeletal conditions who are awaiting orthopaedic surgical consultation have a complex clinical picture and numerous chronic disease risk factors. Given the modifiable nature of many of these risk factors, identifying and addressing them before or while awaiting consultation may improve the health of these individuals.

Interrater reliability of the Clinical Frailty Scale in the anesthesia preadmission clinic

PURPOSE

As many as 30% of patients with frailty die, are discharged to a nursing home, or have a new disability after surgery. The 2010 United Kingdom National Confidential Enquiry into Patient Outcome and Death recommended that frailty assessment be developed and included in the routine risk assessment of older surgical patients. The Clinical Frailty Scale (CFS) is a simple, clinically-assessed frailty measure; however, few studies have investigated interrater reliability of the CFS in the surgical setting. The objective of this study was to determine the interrater reliability of frailty classification between anesthesiologists and perioperative nurses.

METHODS

We conducted a cohort study assessing interrater reliability of the CFS between perioperative nurses and anesthesiologists for elective surgical patients aged ≥ 65 yr, admitted to a large regional university-affiliated hospital in Australia between July 2020 and February 2021. Agreement was measured via Cohen's kappa.

RESULTS

Frailty assessment was conducted on 238 patients with a median [interquartile range] age of 74 [70-80] yr. Agreement was perfect between nursing and medical staff for CFS scores in 112 (47%) patients, with a further 99 (42%) differing by only one point. Interrater kappa was 0.70 (95% confidence interval, 0.63 to 0.77; P < 0.001), suggesting good agreement between anesthesiologists and perioperative nurses.

CONCLUSION

This study suggests that CFS assessment by either anesthesiologists or nursing staff is reliable across a population of patients from a range of surgical specialities, with an acceptable degree of agreement. The CFS measurement should be included in the normal preanesthesia clinic workflow.

Protocol paper for SMART OPS: Shared decision-making Multidisciplinary Approach - a Randomised controlled Trial in the Older adult Population considering Surgery

INTRODUCTION

The Australian population presenting with surgical pathology is becoming older, frailer and more comorbid. Shared decision-making is rapidly becoming the gold standard of care for patients considering high-risk surgery to ensure that appropriate, value-based healthcare decisions are made. Positive benefits around patient perception of decision-making in the immediacy of the decision are described in the literature. However, short-term and long-term holistic patient-centred outcomes and cost implications for the health service require further examination to better understand the full impact of shared decision-making in this population.

METHODS

We propose a novel multidisciplinary shared decision-making model of care in the perioperative period for patients considering high-risk surgery in the fields of general, vascular and head and neck surgery. We assess it in a two arm prospective randomised controlled trial. Patients are randomised to either 'standard' perioperative care, or to a multidisciplinary (surgeon, anaesthetist and end-of-life care nurse practitioner or social worker) shared decision-making consultation. The primary outcome is decisional conflict prior to any surgical procedure occurring. Secondary outcomes include the patient's treatment choice, how decisional conflict changes longitudinally over the subsequent year, patient-centred outcomes including life impact and quality of life metrics, as well as morbidity and mortality. Additionally, we will report on healthcare resource use including subsequent admissions or representations to a healthcare facility up to 1 year.

ETHICS AND DISSEMINATION

This study has been approved by the Hunter New England Human Research Ethics Committee (2019/ETH13349). Study findings will be presented at local and national conferences and within scientific research journals.

Risk Assessment

Purpose of Review

The central question of preoperative assessment is not “What can be done?” but “What should be done and how?” Predicting a patient’s risk of unwanted outcomes is vital to answering this question. This review discusses risk prediction tools currently available and anticipates future developments.

Recent Findings

Simple, parsimonious risk scales and scores are being replaced by complex risk prediction models as high-capacity information systems become ubiquitous. The accuracy of risk estimation will be further increased by improved assessment of physical fitness, frailty, and incorporation of existing and novel biomarkers. However, the limitations of risk prediction for individual patient care must be recognized.

Summary

Risk prediction is transforming from clinical estimation to statistical science. Predictions should be used within the context of a patient’s baseline risk (life expectancy independent of surgery), personal circumstances, quality of life, their expectations and values, and consideration of outcomes that are meaningful for the patient.

Resistance of disposable drapes to bacterial penetration

PURPOSE

To test the bacterial penetrability of disposable non-woven drapes used specifically for total hip arthroplasty.

METHODS

12 round agar plates were inoculated with 107 colony-forming units/ml of coagulase-negative staphylococci (CNS) and incubated in air at 37 degrees Celsius for 18 hours to obtain a semi-confluent growth of organisms. Six brands of disposable drapes were tested; each was assigned to 2 plates. Each disposable drape was placed between a round agar plate and an inverted square agar plate filled with blood agar. After 30 and 90 minutes, the square agar plates were removed and incubated for 48 hours and inspected for growth of CNS.

RESULTS

Bacterial penetration was time dependant. Certain brands of drapes were more impenetrable than others; none was impenetrable at all time points, but most remained so or allowed passage of fewer than 100 colony-forming units at 90 minutes.

CONCLUSION

It is recommended that drapes be rigorously tested with regard to their resistance to bacterial penetration.
